The $80 neutral benchmark — flawless tone to some, 'where's the bass?' to others.
$80 1DD+3BA hybrid IEM. Not the dual-DD Truthear x Crinacle Zero / Zero:RED, nor the Hola, Nova, Gaia, or the newer Pure (a successor that tames the Hexa's treble).
The Truthear Hexa arrived in 2022 as an $80 hybrid — one dynamic woofer and three balanced armatures — and quickly became the budget IEM that every other budget IEM gets measured against. A compact resin shell with a metal faceplate, tuned to hug a neutral, Harman-ish target, it drew rare praise from the people who measure these things: Crinacle's A+ for tone, a five-star from Super* Review, an 'insanely good' from Resolve.
It has spent the years since as the genre's reference point for 'neutral done right' on a budget — and as a lightning rod. The perennial arguments are whether its bass is Goldilocks-clean or simply anemic, whether the upper treble is airy or glary, and whether 'neutral' here means honest or just boring. Plenty of opinion to average; plenty of disagreement to map.
An $80 1DD+3BA hybrid tuned close to a neutral, Harman-ish target, and for years the budget IEM others are benchmarked against. Reviewers broadly agree on its clean, vocal-forward midrange, its exceptional tone-for-the-price, and a comfortable compact shell let down by a thin cable — and equally agree the soundstage is intimate and the dynamics modest. The fault lines are bass (clean and sufficient vs anemic and 'lo-res'), upper treble (smooth and airy vs bright and glary around an ~8 kHz peak), and the neutral signature itself (reference-grade vs simply boring). It's a tuning benchmark, not a technical giant-killer — and newer budget rivals have since narrowed its lead.
The headline strength and the most-repeated praise — clean, clear, vocal-forward and natural. The minority caveat is a light note-weight that some find lean.
“Clean, clear vocals with decent detail.”

“Note-weight can be light.”

Forward upper-mids with ~8.5 dB of pinna gain at 3 kHz, tracking a neutral target (Twister6, IEC711).
Everyone agrees it's neutral / neutral-bright and measures close to a reference target. They split hard on whether that reads as honest and clean or simply safe and boring.
A neutral-warm signature with a 'very linear 7dB sub-bass shelf' (Twister6, IEC711); Crinacle grades tone A+, and RTINGS scores it 'Balanced'.
⚠ vs. listeners — 'Reference' vs 'boring' is one neutral tuning judged against taste: warm/bass-leaning listeners score it lower, neutral fans higher.
“Good neutral is hard to find in this price, this is one of the gateways”
DeeJay (IEMRanking user)
“One of the most boring headphones I have ever listened. Everything is just too flat and uninteresting.”
reader comment, RTINGS
The single most-argued axis. A clean sub-bass-led low end with a soft attack — heard as just-right and non-boomy by some, as anemic and lacking slam/texture by others.
A linear 7 dB sub-bass shelf (Twister6, IEC711), but the 'punch and impact are both on the softer side of reference-neutral'; Precogvision grades bass C+ and calls it 'lo-res'.
“Bass quantity sits in a Goldilocks zone—never boomy—though the attack is a touch soft”
Super* Review (via IEMRanking)
“KING. Special. Inoffensive. But honestly where bass?”
Jaytiss (via IEMRanking)
Built on BAs with an upper-treble peak. One camp hears it as smooth, airy and well-extended; another as bright, glary and fatiguing — strongly tip- and ear-dependent.
On the B&K 5128, the upper-treble peak is 'very noticeable' and 'sharpens hats and cymbal notes' (Headphones.com); Twister6 sees a single ~8 kHz peak on IEC711. Foam tips tame it.
⚠ vs. listeners — Headphones.com cautions that 'treble measurements are unreliable and very dependent on an individual's anatomy and the tips chosen' — so smooth vs glary is largely an ears-and-tips story.
“treble that's smooth yet well-extended without plasticky BA glare”
Super* Review (via IEMRanking)
“Too much low treble with a bit of glare but otherwise really great”
Resolve (via IEMRanking)
Strong technical performance for the price — a budget benchmark — but not a giant-killer: a clear step below pricier sets, and some hear the detail as partly treble-led.
“Great detail for price and new benchmark below $100”
Jays Audio (via IEMRanking)
“A mini B2 minus the good stuff.”
Shuwa-T (via IEMRanking)
Twister6: 'pretty good detail retrieval and separation for its neutral-warm signature and its asking price'; reviewer technical grades cluster around B-/C+ (IEMRanking).
Most hear it as intimate, narrow, even 'crammed' — average for the price and not the holographic stage some want, though a few find it well-balanced.
“Somewhat crammed soundstage”
Shuwa-T (via IEMRanking)
“the soundstage width is more on the intimate side because of dipped lower-treble and warmer upper-treble presentation”
Twister6
Solid and a genuine strength for competitive gaming (directional cues), but not the sharpest, pinpoint imaging in its class.
“Imaging is solid (often praised for gaming cues), but not the sharpest “pinpoint” in its class.”
IEMRanking (15-review aggregate)
Modest — controlled and a little flat rather than punchy, with a soft attack and light note-weight. A recurring, broadly-agreed limitation.
“More controlled/flat than punchy—common complaint is limited slam/dynamics.”
IEMRanking (15-review aggregate)
Dynamics graded C+ on average (IEMRanking); the dynamic driver's soft attack limits slam.
Mostly positive — light (~6 g), compact, low-profile, even sleep-friendly. The recurring caveat is fit/seal: the longer nozzle wants a deep insertion that can break the seal for some ears.
“The shells are quite small and fit my ears extremely comfortably. They're very easy to live with for long listening sessions.”
Twister6
“it wants to go for a deeper insertion, however for me it breaks the seal of the included eartips”
audioreviews.org
~6 g per side, compact resin shell, 6.35 mm nozzle (specs); recessed 0.78 mm 2-pin limits cable swaps.
Tip-dependent: excellent with foam tips, but impressions split — measured as outstanding by one reviewer, merely average by another with stock silicones.
“improved noise isolation: these are the pair to pick if you plan to wear your IEMs in places like busy offices”
RTINGS
“Isolation is average, they don't fill your outer ear so I am not surprised by this.”
audioreviews.org
With foam tips, SoundGuys measured isolation topping out around 44–54 dB above 5 kHz; stock silicones isolate less.
A solid smoky-resin shell with a metal faceplate that reviewers like — 'no frills' but well made — let down by a thin, tangly cable, a plain case, and a recessed 2-pin.
“the build quality is actually pretty sweet for the price”
Twister6
“kit is mixed (thin tangly cable, plain case, recessed 2-pin)”
IEMRanking (15-review aggregate)
The strongest agreement of all — a long-standing price/performance benchmark at ~$80. Dissent is thin: a few find the hype overblown, and newer rivals have narrowed the lead.
“Great value for $79”
Audionotions (via IEMRanking)
“Honestly cannot understand the hype”
